Abstract:The Bailey bridge is a space truss structure composed entirely from prefabricated panels which are assembled in situ by placing pins through the holes of the lugs at the ends of the panels’ chords. The present paper deals with the fatigue assessment of these panel pins. The bridge is modelled as 3D space truss using beam elements and the Fatigue Load Model 3 (FLM 3) is chosen to verify the fatigue life of the pin detail. The model is analysed using both static and dynamic analyses and the range of the shear stresses on the pin are calculated. Finally, following the λ-method, recommended in EN 1993-2: 9.5.2, the fatigue strength of the pin is checked.
